Instructions

  1. Spray skillet with cooking spray. Heat to medium heat.
  2. Sprinkle chicken with thyme, rosemary (optional), salt, and pepper.
  3. Place chicken in the preheated skillet and cook 4 minutes on each side, or until chicken is lightly browned.
  4. Add the chicken stock and sherry. Bring to a boil.
  5. Cover and reduce heat; simmer for 10 minutes.
  6. Add mushrooms and cook uncovered until the mushrooms are tender.
  7. Remove the chicken and mushrooms from the pan; keep warm.
  8. Add the half and half and mustard to the skillet. Whisk together to blend. Cook 1 minute or until thoroughly heated. If desired, thicken sauce with cornstarch -- be careful -- it is easy to get it too thick.
  9. Return the mushrooms to the skillet, and serve the sauce and mushrooms over the chicken.
